HX83485-S
ZHHXDZ · RS-485 / RS-422 ICs · SOP-8
HX83485-S from ZHHXDZ, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output: RO is high when V(A)-V(B) is at or above -50mV and low when V(A)-V(B) is at or below -200mV. |
| 2 | RE | input | Receiver output enable, active low per the datasheet: when RE is high the receiver is turned off, and when RE is high and DE is low the whole chip enters shutdown. |
| 3 | DE | input | Driver output enable, active high: when DE is high the driver output is enabled, and when DE is low the driver turns off and the output enters a high-resistance state. |
| 4 | DI | input | Driver data input: with DE high, DI high drives A high and B low, and DI low drives A low and B high. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | A | bidirectional | Driver output / receiver input, non-inverting bus line A, with ESD protection rated at ±15kV human body model. |
| 7 | B | bidirectional | Driver output / receiver input, inverting bus line B, with ESD protection rated at ±15kV human body model. |
| 8 | VCC | power_in | Supply pin for 3.3V/5V operation; the DC characteristics are specified at VCC = 3.3V ±5% and the absolute maximum VCC is +6.0V. |
